B Block Odds Lab

Weekend challenge

Before you buy or tune another miner this weekend, run the odds.

The weekend itch is real: a higher frequency, a second board, a desk miner, a better fan, a new pool. This challenge keeps it honest. Run the math, post the result, then decide whether the upgrade is actually worth it.

The three-minute challenge

  1. Open the Block Odds calculator.
  2. Enter your real hashrate, watts, power cost, hardware cost, BTC price, and current difficulty.
  3. Screenshot or copy the yearly chance, expected time, annual net expected value, and hardware payback.
  4. Change one thing: more hashrate, lower watts, a better fan, a second board, or a different miner.
  5. Share the before/after result with the question: did the upgrade move the odds enough to matter?

Weekend lottery-mining challenge: before buying another Bitaxe, NerdMiner, fan, PSU, or tuning change, run the actual block odds. Post your hashrate, watts, yearly chance, expected time, and whether the upgrade moved the odds enough to matter. Free calculator: https://blockoddslabs.com/weekend-mining-challenge.html
Bitaxe thread reply 
Before pushing that Bitaxe setting, compare stable watts vs pushed watts. If yearly odds barely move but heat/rejects climb, the stable setup might be the better win: https://blockoddslabs.com/bitaxe-odds-calculator.html
NerdMiner comment 
NerdMiners are awesome for learning, but the odds are the point. Run the hashrate and see the expected time before calling it a profit play: https://blockoddslabs.com/nerdminer-bitcoin-odds.html

Substack note 
This weekend I am using a simple rule for small Bitcoin miners: no tuning change, second board, or desk-miner purchase until the odds are run first. Block Odds Lab now has a weekend challenge page for sharing before/after results: https://blockoddslabs.com/weekend-mining-challenge.html
